Abstract

An apparatus (20) such as a light source is disclosed which has an OLED device (205) and an index bridging elastomer (230) disposed on the substrate (208) or transparent electrode of said OLED device (205) and on the exterior of said OLED device. The elastomer (230) bridges the refractive index between the substrate (208) and an intended target for said apparatus (200).
